Passenger Reports

There was some noticeable movement on the climb out that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.

First-time flyer · May

Some light chop crossing the ridge — seatbelt sign came on for maybe 20 minutes but nothing to worry about. Typical for this route in June.

Regular traveler · June

A few bumpy patches on the climb out, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.
